As an owner of quite a few 721/2s and a 700 as well as a bunch of 99s, it was interesting to note that old 99 never brought up the spring in the action of a 99 making it especially unsuited for the 22-250 and 284 (unless you consider 3 reloads from new brass acceptable).
IME the 721/2 is a superior rifle to any 700 which (with great effort) the bolt handle can fail. The "failed" extractor he showed showed all the signs of a way too hot load (note the case was not pictured), I have never had a 721/2 extractor fail even when tearing the rim off a way too hot 300 H&H. I did have a riveted 700 one fail in a 244 H&H I built. That cartridge is a rocket ship and runs off the scale pressures. A SAKO extractor fixed the problem for good.
A 721 dropped in any of the many 700 LA stocks sold by Numrich is not much work and is better suited to scope use.
Proceed, life is too short to debate this further.
best, Larry
